Letters Patent No.'88,690, dated April 6, 1869.

IMPROVEMENT IN GRAIN-SEPARATOR.

Be it known that I, PELEG BARKER, of the city of Battle Creek, in Calhoun county, State of Michigan,

chines for Threshing, Separating, and Cleaning Grain; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part thereof, in which Figure l represents a longitudinal section:

Figure 2 represents 'a top plan; and

Figure 3 representsa side elevation.

The nature of my invention relates to the manner in which I have constructed and arranged the raddlcs or slatted carrying-apronsin connection with the inclined trunk, so as to separate and carry off the straw without carrying. oif or out of the machine the grain with said straw, using one ofsaid raddles to convey the grain tothe of grain, 860., back again to the threshing cylinder, grates, or perforated floors, to prevent the fine straw from filling up and choking or stopping the raddles, and the agitator r, placed in the raddle n, to cause a perfect separation of the threshed grain from the straw.

I construct my machine similar to the Pitts machine,

except in place of an apron, or grain-belt for conveying thgiain and chafi', I use a secondary raddle, onslotted belt 0, with a tight floor 11 below, which said raddle runs in anopposite direction from'the others. This raddle exclusively elevates the grain and chafi' to the cleaner, as is shown in my drawings, and is not used or intended to carry straw.

I place directly above said raddle, or slotted belt 43, another open raddle, or slotted belt, which carries the straw from the grate back of the threshingcylinder, and delivers the same on raddle a, which carries it clear from the machine. These ,raddles 1', and a, are each provided with a perforated floor, to prevent the fine straw from filling up and choking or stopping the raddles.

I use the agitator r to shake the raddle in such a manner that any threshed or shelled grain that might be in the straw would be shaken out. This agitator swings forward and backward on the rods 8 s, by means of the crank t, fig. 3. It will be readily observed that as it swings it strikes the raddle, as is shown in fig. 1, which causes a violent agitation of the same, keeping the straw tossing up and down as it passesa long.

I use an elevator A for returning unthreshed heads of grain, 860., to the cylinder to be run through again. The floor of the elevator is notched, and has sides to hold the grain in, and is made to slide forward and back ward on the ways 11, by means of the shaft h. These ways 2: are placedinsuch an angle that as the elevator moves forward and backward it has a tossing mo tion, which throws the grain along from notch to notch until it is discharged into the thresher.

The operation of my machine is that the grain is fed to the thresher in the usual manner. The cylinder threshes the grain from the straw, which is carried away by means of raddlesas described; the grain fall through thefgrates under the cylinder, thence is allowed to fall to the tight floor d, from whichit is carried, by means of raddle. c, to the cleaner, also any grain that may fall or be shaken from raddle 1? falls through raddle 0130 the floor, and is carried up to the cleaner.

The raddles,&c., are driven or rotated by means of suitable belts and pulleys or gearing-and the elevator A carries the nnthreshed heads of .grain, &c., back to the thresher as above described.

Having thus described my invention,

'What I claim as new, and desire to secure by Letters Patent, is as follows, to wit: a

1. The two open Paddles. c and'i and the grain-floor or trunk, combined together, and arranged in relation to the thresher and cleaner, as set forth and shown.

2. Also, the elevator A, fig. 3, for the purpose of elevating unthreshed heads of grain, 850;, back to the thresher, substantially as described.

3. Also, the agitator r, when constructed and oper ting as described, for the purposes set forth.
